Letters Patent in England, No. 276, dated January 19, 1882, and sealed April 11, 1882,) of which the following is a specification.

This invention has reference to further impiovements on my former inventions for improvements in the method of and apparatus for Ventilating sewers and drains, and for treating the gases therefrom,77 improvements in the method of and apparatus for Ventilating buildings, water-closets, ships or vessels, and the like,77 and improvements in and applicable to chimneys or dues, parts of such improvements being applicable to other purposes,7 respectively, for which I am applying for Letters Patent; and the present improvements consist, ehietiy, in certain apparatus employing a jet or jets of water for producing an induced current for carrying off the foul air and gases from water-closets, urinals, drains, sewers, and the like, the said water also serving for washing or purifying the said foul air and gases before the same escape.

In carrying out my improvementsI employ a jet or jets connected with a suitable supply of water, and so placed in a tube open to the receptacle or the like, from which the gases or other noxious products are to be drawn and treated, that an induced current will be produced either directly or spiral] y in such a manner that the said gases or other products will be abstracted and washed before being discharged.

In order to enable my invention tobebetter understood, I will proceed to describe the same by reference to the accompanying drawings, in which- Figure 1 is a sectional elevation showing one arrangement for carrying out my invention as applied to a water-closet; Figs. 2 and 2*, sectional elevations showing a similar arrangement applied to a urinal. Fi 0. 3 is a sectional elevation showing the present improvements adapted to a receiver employed in ventithe water-closet pan, communicating by means -of the connection b with the vertical tube c,

providedwith a nozzle, d, inserted therein,

having its mouth directly opposite the foulair connection and in communication with a supply of water. c opens into a boX or receiver, e, having a trappeddischarge-pipe,f. gisaconnectionfor the outlet or discharge tube' for the washed or purified air or gases. By this construction, if water under pressure be supplied to the nozzle d by any suitable means, it will be discharged in a series of jets or spray into the vertical tube c, directly opposite the entrance of the foul-air connection, and this incoming jet or spray will thereby come directly against and in forcible contact with the foul air and gases immediately u pon their entering the vertical tube c, and will produce an induced current, which will draw or abstract the foul and other air and gases from the pana, and the spray or jets will carry the said air and gases along into the box e, from which they will escape through g, after having been washed by the Water during their passage. The water from the box e is discharged through the outlet f, carrying with it any matters condensed from the said air and gases.

In Figs'. 2 and 2 I the hereinbefore described arrangement is shown applied to urinals, a a being the basin. The operation,being substantially the same as that described by reference to Fig. 1, needs no further description.

In Fig. 3, which shows a method of Ventilating a sewer or drain, A is an ordinary sewer; B, a receiver similar to that described in the said specitication of my improvements The lower end of the tubev in the method of and apparatus for ventilatceiver into the vertical tube c, provided with a nozzle, d, as in Figs. 1 and 2. By this arrangement the air or gases will be drawn from loo the receiver by the action of the jet of Water invention and suitable means of carrying the into the tube c, and will be Washe'd before besaine into effect, I would have it understood ing discharged through the outlet g. that what I claim is In theseveraliiguresl,2,2*,and3ofthe draw- The combination, with the structure to be 2o 5 ings I have shown and I have described the ventilated, of the receiver B, supplied with a nozzle d, placed vertically in a vertical tube. purifying material through which the foul air I would, however, remark that the nozzle may or gas passes, the Water-nozzle d, having its be placed at any suitable angle, or that a simmouth located as described with reference to ple jet or jets of Water may be provided in the inlet of the tube through which the air or 25 1oy any suitable position in the side of the tube, gasis driven and washed, chamber e, and pipes with the object of producing a spiral current g andf, all as and for the purposes described. y
